DADiSP provides a number of functions for identifying series characteristics. These functions place a cursor on the point location of your data graph that fits the function specification.
The peak and valley functions accept several optional arguments. For instance, all functions require an initial window reference argument in which the peak/valley search is to be performed. The second argument is a threshold value, mandatory only for FPEAK and FVALL. The third argument is an optional width for the peaks (number of points above the threshold). Note that the peak/valley functions do not return any values, but simply present a cursor position.
